面扫 特殊相机BVC2951U

By using prism spectroscopic imaging technology, this ESD phenomenon visualizing camera, BVC2951U, works very well to monitor the place of the electrostatic discharge on the production site. BVC2951U captures NUV rays generated at the time of discharge using ultra-sensitive camera, and it is able to monitor where and when the low voltage ESD (200V as minimum) occurs.

BVC2951U is a build-to-order product.


BVC2951U consists of two kinds of sensors, one for taking the visible image of the object and the other for detecting electric discharge phenomenon. It uses a spectroscopic technology adopting a mirror to split the visible light (400nm to 700nm) and NUV rays (200nm to 400nm). BVC2951U has two sensors, a visible sensor with 640 x 480 pixels and an ultra-sensitive UV sensor, and one fixed focal lens. As two sensors and one lens are all in one package, images from two sensors are in the same field of view, which enables BVC2951U to precisely detect the originating point of the ESD damage.

ESD means ElectroStatic Discharge, and when the ESD occurs, it generates NUV rays from around 200nm to 400nm (UV-B). Since the light energy produced by ESD is very small, the ultra-sensitive sensor is required to capture this phenomenon.
